Abstract
1511882 Electromagnetic switches; automatic circuit-breakers SQUARE D CO 23 April 1975 [29 April 1974] 43654/76 Divided out of 1511881 Heading H1N The Specification describes a combined automatic circuit breaker and electromagnetic overload switch as in parent Specification but the claims are directed to the armature 158 of the switch controlling a pin 161 situated between the pivot mountings 169, 171 of two contact blades 152, 154 which are spring biased to engage each other and operatively movable, on armature attraction to a yoke 156, by links 163, and pins 166, 167 to open the contacts.
